Purchased on recommendation of a friend, who swears it helps her. I was very sceptical, but started to use with an open mind. At this point in the monthly, I lack energy, feel tired, run down, and a bit low in mood. My sleep pattern is non existent. After using for 8 days. I can report a marked improvement, in my general mood, I definitely sleep better, and don’t feel as tired. I can’t explain how this works scientifically, but it works for me
